A two-vehicle crash involving a truck towing a cattle trailer is causing extreme delays on eastbound Interstate 10 near Vail, officials say.
One person was taken to a hospital, according to the Arizona Department of Public Safety.
Troopers are now trying to secure the cows that got out of the trailer after it rolled onto its side. It's unknown if any animals were injured, the department said.
The Arizona Department of Transportation reported the vehicle crash at milepost 283 around 5:40 p.m.
It initially caused a backup of nearly three miles.
The eastbound right lane was reopened shortly before 11 p.m. The full road closure had caused an extended backup from milepost 287 to Houghton Road, ADOT said.
There are still extreme delays on I-10 EB east of Tucson (near Vail). The right lane's still closed due to earlier crashes and animals in the road. The backup now extends from Houghton Road to just past MP 287. Use alternate routes or delay travel. #aztraffic #tucson pic.twitter.com/THSgJpVdwL
